Subject: * apt-pkg/deb/debindexfile.cc:   - Use FileFd::Size() instead of
 stat()ing the sources/binary/translations     indexes directly, so that we
 have transparent handling of gzipped     indexes.

Subject: * apt-pkg/contrib/fileutl.cc:   - Fix FileFd::Size() for gzipped
 files to give the size of the     uncompressed data. This fixes cache
 progress building progress going way     over 100%.
